Hi Randy,
We have not yet implemented this functionality in version 2.0 of SyncroSim (ST-Sim 3.1), the reason being that the modular architecture that allows for different modules makes this feature a bit more complicated to include in the main SyncroSim menu. However, we hope to add it in the near future. In the meantime, you could copy the entire project or scenario and then under project definitions, delete the strata that you are no longer interested in working on for that particular library. Let me know if that makes sense, or if you have any questions.
Regards,
Leonardo
